5 Signs You Need New Tires Before a Southeast Kansas Winter
Before the first freeze, check five things: tread depth (under 4/32 inch is too low for winter), tire age (look hard at anything over six years), sidewall cracks, uneven wear, and a pressure light that keeps coming back. Any one of them is a reason to replace tires before ice season.
Southeast Kansas winters don't usually bury us in snow. What they bring is worse for tires: freezing rain, black ice on bridges and overpasses, slush on county roads, and 40-degree temperature swings in a day. Tires that were fine in August can be the weak link in January. Here's what to check, and what each sign means.
1. Is your tread deep enough for wet and icy roads?
If you can see the top of Washington's head when you put a quarter upside down in the tread, you're at or below 4/32 inch, and that's too thin for winter. Tires are considered worn out at 2/32 inch (the penny test: Lincoln's whole head showing), but grip on wet roads and slush falls off well before that, because there's not enough groove depth to push water and slush out from under the tire.
Check in three spots across each tire: the inside, the center and the outside. If one spot is much lower than the others, that's sign number 4.
2. How old are your tires?
Find the four-digit date code on the sidewall, after the letters "DOT." "2419" means the 24th week of 2019. Rubber hardens as it ages, and hard rubber doesn't grip cold pavement well, even with plenty of tread left. Many tire makers recommend a close inspection once tires reach six years old, and replacement by ten no matter what.
This matters most on vehicles that don't get driven much, like the second car, the farm truck, or the trailer. They're the ones that look fine and aren't.
3. Are there cracks in the sidewall?
Fine cracks in the sidewall or between the tread blocks ("dry rot") mean the rubber is breaking down. Kansas summer sun and ozone are hard on tires, especially ones that sit outside. Small surface cracks are an early warning. Deep cracks, cracks you can fit a fingernail into, or any bulge or bubble in the sidewall mean the tire should come off now. A bulge means the internal structure has failed, and it can blow out without warning.
Gravel and chip-seal county roads add a second risk: cuts and gouges in the sidewall from sharp rock. A sidewall cut can't be repaired. See when a tire can and can't be fixed.
4. Is one edge of the tread wearing faster?
Uneven wear means something else is wrong, usually alignment, and new tires won't fix it on their own. Patterns to look for:
- Inside or outside edge worn: alignment (toe or camber) is off. Wheel alignment
- Center worn more than the edges: running too much air pressure.
- Both edges worn: running too little air.
- Scalloped or cupped patches: worn shocks, struts or balance problems. Suspension and steering
If you replace tires that wore unevenly, have the cause fixed at the same time, or the new set will go the same way.
5. Does your tire pressure light keep coming back?
Air pressure drops about 1 psi for every 10°F the temperature falls, so the first cold snap often turns the pressure light on. That's normal. Air up to the pressure on your door-jamb sticker, checked in the morning when tires are cold.
But if the light comes back after you've aired up, one of your tires has a slow leak: a nail, a leaking bead, or a bad valve. Running a tire low in cold weather wears it fast and makes it more likely to fail. If the light flashes for a minute before staying on, it's usually a sensor with a dead battery. We fix all three. See flat repair.
What should you do if you find one of these signs?
- Don't wait for the first ice storm. The week of a big freeze is usually a busy week at any tire shop.
- Call with your tire size (it's on the sidewall) so we can check stock or order: 620-331-3730.
- Ask for an alignment check if your old tires wore unevenly.
- Replace in pairs or sets. On four-wheel and all-wheel drive, matched tires protect the drivetrain.

Frequently asked questions
How much tread do I need for winter driving?
At least 4/32 inch. Tires are considered worn out at 2/32 inch, but traction on wet and slushy roads drops off well before that. Use a quarter: if you can see the top of Washington's head, you're at or under 4/32.
Do I need snow tires in Southeast Kansas?
Most drivers here do fine with good all-season or all-terrain tires with plenty of tread. Dedicated winter tires make sense if you drive early mornings on untreated rural roads or bridges often.
Why does my tire pressure light come on when it gets cold?
Air pressure drops about 1 psi for every 10°F drop in temperature. A tire set correctly on a 70-degree afternoon can be low enough on a 20-degree morning to trigger the light. Check and adjust when it's cold.
